Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen
Advanced Materials, EarlyView.Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

A Noninvasive Approach to Study Localized Forces in 3D Epithelia
Advanced Materials, EarlyView.Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Pre A∗-Algebras and Their Applications in Fuzzy Set Theory
International Journal of Mathematics and Mathematical SciencesThis paper studies Pre A∗-algebras and their role as an algebraic foundation for fuzzy set theory. By relaxing the key Boolean axioms of distributivity and complementation, Pre A∗-algebras provide a robust algebraic structure for reasoning with ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Constructing implication functions from fuzzy negations
Proceedings of the 8th conference of the European Society for Fuzzy Logic and Technology, 2013 A class of implication functions is constructed from fuzzy negations. The interest of this new class lies in its simplicity and in the fact that when N is Idsymmetrical, the corresponding implication agrees with the residuum of a commutative semicopula.

TacScope: A Miniaturized Vision‐Based Tactile Sensor for Surgical Applications
Advanced Robotics Research, EarlyView.TacScope is a compact, vision‐based tactile sensor designed for robot‐assisted surgery. By leveraging a curved elastomer surface with pressure‐sensitive particle redistribution, it captures high‐resolution 3D tactile feedback. TacScope enables accurate tumor detection and shape classification beneath soft tissue phantoms, offering a scalable, low‐cost ...

On the measure of fuzziness and negation. II. Lattices
Information and Control, 1980 We propose that the measure of fuzziness of a concept is related to the distinction between the concept and its negation. In this paper we are concerned with the situation in which our objects lie in a lattice. We introduce the lattice concept of betweenness to operationalize our definition. We investigate properties of this concept of fuzziness.

Children\u27s Understanding of the Semantics of Negation [PDF]
, 2010 The central focus of this project is to discover children’s understanding of the semantics, or meaning, of negation. Children’s knowledge of negation develops, in part, by directing attention away from a word to something else (i.e., contrast classes ...

Negation in vernacular Brazilian Portuguese [PDF]
, 2013 textAs Haegeman and Zanuttini (1996:117) discuss, when two negative elements are present in a specific syntactic domain, two possible situations may arise: "(i) the two negative elements may cancel each other out, or (ii) the two elements may ...
